The CSNE151 Honeywell Current Sensor is compact and light in weight and can measure AC, DC and impulse currents. Current sensors are mechanical instruments that detect and convert current. The output voltage is easily measurable and is proportional to the current. These CSNE151 sensors are used in variable speed drives, over-current protection, ground fault detectors, current feedback control systems and robotics.

Current sensing devices are important in many instrumentation and power systems. This Closed Loop Current Sensor is also used in UPS and telecommunication power supplies, welding power supplies, automotive - battery management systems and wattmeters.
